CHARLES A. TUCKER, OF ISLIP, NEW YORK.

ELECTRIC TEMPERATURE-REGULATOR.

SPECIFICATION forming part of Letters PatentNo. 302,215, dated July 15,1884.

Application filed March 20, 1884.

Islip, in the county of Suffolk and State of New York, have invented anew and Improved Electric Temperature-Regulator, of which the followingis a full, clear, and exact description.

The object of my invention is to provide a,

new and improved device for regulating temperature by means ofelectricity.

The invention consists in the peculiar construction and arrangement ofparts, as hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front View of my improved temperature-regulator. Fig. 2 isa cross-sectional elevation of the same on the line 00 00, Fig. 1. Fig.3 is a face view of the end of the regulator and part of thewindow-frame.

A frame, A, of such-length that it can fit in between the standards ofthe window-frame, is provided with a central standard, B, and to the endstandards and the said central standam of the said frame downwardly andoutwardly inclined slats O are secured, midway 0 between which slats Oslats D are pivoted,

which slats D can be swung in a horizontal position to close theopenings between the slats C, or can be swung in a position parallelwith the slats C. The inner or adjoining ends of the slats D areconnected at their inner edges by wires E, which several wires E arepivoted in one upright rod, F, on the inside of the frame. The lower endof the rod F is pivoted to one end of a lever, G, on the opposite sideof the pivot of which an armature,H, is fastened, which is located abovean electromagnet, I, held on the bottom of the inside of the frame. Aspring, J, draws the rod F downward. Two spring-strips, K, are securedon one end of the frame A at the top and bottom, and are connected bywires a b with the opposite ends of the magnet I. On the inner surfaceof one of the standards L of the window'frame two metal plates, M, aresecured,

(No model.)

of which one is connected by a wire, d, with a thermometer, N, the wire(I being fused into the thermometer-tube at the maximum degree of heatdesired in the room. The bulb of the mercury-tube is connected by awire, 9, with a battery, 0, which is connected by a wire, h, with theother plate M on the window-frame.

If the frame A is placed in the windowframe either above or below thesash, accord ingly as the plates M are arranged in the window-frame, thespringstrips K come in contact with the plates M, thus connecting thetwo terminals of the electro-magnet with the thermometer-tube.

If the temperature rises in the room, the mercury rises in thethermometer-tube and closes the circuit, whereby the magnet I becomesexcited and attracts the armature H. Thereby the long end of the leverGis thrown upward and moves the rod F upward, which swings the slats Dinto position parallel with and midway between the slats 0, thuspermitting the cold air to pass into the room and the warm air to passoff. As soon as the tem-. perature falls the circuit is broken, thearmature H is released from the magnet, and the spring J draws therod Fdownward, thereby swinging the slats D against the edges of the slatsG-that is, in horizontal positionsso that they close the openingsbetween the slats C.

The above-described frame can also be held in light openings or inopenings in the wall provided to receive these frames.

Having thus described my invention,wl1at I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the frame A, of the downwardly and outwardlyinclined fixed slats O, the pivoted slats D between them,

'bar F, connecting the slats D, the spring J,

connected with the bar F, the pivoted lever G, carrying an armature, H,and connected with the bar F, the electro-magnet I, the thermometer N,the battery 0, wires connecting the magnet with the thermometer and thebattery, and a wire connecting the thermometer with the battery,substantially as herein shown and described...

2. The combination, with a frame having thermometer and battery beingconnected by pivoted slats, of a lever and an electric inaga wire,substantially as herein shown and de 10 net for shifting the pivotedslats, springscribed. pieces secured on the end of the frame, and

I connected with the terminals of the electro- CHAS ER magnet platessecured in the window-casing, Vitncsses: of which plates one isconnected with a bat- OSCAR F. GUNZ, tery and the other with athermometer, the O. SEDGWIOK.
